The market is not really 'intentional', but rather caused by mechanical structures.

Slippage is triggered by the system and executed at market price; as long as the volume is large, it will:

Eat up the limit orders

Impact prices

Drive the direction of the market

Result in a trend-driven large K line.

This is pure mathematics, pure mechanism, not 'who is manipulating'.

In summary, the whole mechanism can be summarized in one sentence:

Large slippage = Large market orders → Market orders only have one direction → K line surges in that direction.
